Description

Septum post

The present invention relates to a post of partition that incorporates mechanical and acoustic properties improved.

A usual construction technique for manufacture of building walls, and in particular walls interiors, is to hold sheets of material for walls, as per example partition plate, to vertical stringers of section in channel known as partition walls. The document US-A-6,389,916 discloses a post of partition of the indicated type. Typically, each post is subject to a stringer or channel secured either to the floor or to the ceiling of the room in which the interior wall is being built. This septum construction technique is at the same time relatively simple and inexpensive and also allows the possibility, if requires, to subdivide existing interior spaces, by example by altering the use of the existing building.

More than holding a sheet of partition plate to both sides of the same partition wall, it is usual practice use two rows of parallel partition posts and hold a single partition wall to the outer faces of each of the posts couplets. This is done to create a relatively free space wide within the resulting wall that provides a Isolation to low frequency sounds.

However, this type of construction of "double pole" generally requires some form of brace that is fixed between parallel posts covering the free space to provide the structure with sufficient strength. To the same time that the brace provides a connection necessarily rigid between posts, also provides a transmission point of connection of the sounds, reducing the insulating performance to the wall sounds. Although attempts have been made to resolve this problem by providing braces with resilient portions intended to reduce their sound transmission properties, It is a solution that is far from being totally satisfactory.

Also, when using a double row of posts for a single partition, the cost of the material used, and the time required to install the two rows of tracks, it increases considerably with respect to the costs that the use of a single post construction.

In accordance with the present invention, provides a partition post according to claim one.

It is therefore possible to provide a channel section partition wall post in which the only sheet which interconnects the two side walls to which they will be fixed the corresponding sheets of material for walls, has a cross section substantially corresponding to a letter C with elongated side arms.

The substantially semicircular member has a plurality of rows of elongated grooves formed within it, the adjacent rows being longitudinally offset between yes. The slots preferably have at least twice the length of the interconnecting portions of the member substantially semicircular. Optionally, the diameter of the substantially circular member is proportionally equal to the width of each of the first and second members planners

At least one of the side walls, and preferably both, it can have an angled longitudinal groove acute, for example, a V-shaped groove, which extends over the minus a portion of the length of the pole. Additionally, the acute angle groove is located substantially midway transversely to the width of the side wall.

Preferably, at least one of the surfaces from the side walls facing away from each other It has a plurality of depressions formed in it. Additionally, depressions can be pyramidal. Additionally or alternatively, depressions may be formed by a deep knurling process and / or a corrugated process Depressions increase the stiffness of side walls, thus facilitating the clamping of the plates of partition to the post.

Optionally, a non-woven gender partition it can extend transversely to the opposite edges of the curved member, thus defining a closed space between the non-woven gender and the curved limb, and a second gender not tissue can extend between opposite side walls.

Alternatively, a sheet of a material that have sound insulating properties can extend between the opposite side walls. The material sheet can comprise glass wool or mineral wool mat, polyester wool not woven, fluffy plastic, or any other appropriate material sound absorbing

Figure 9 schematically illustrates a post partition construction using an agreement post with an embodiment of the present invention.

Figure 1 illustrates, in a plan view, a first embodiment of the present invention. The post 2 has a first and a second side walls 4, 6 at which, in use, can be sanded a sheet material for walls, indicated by dotted lines 8, 10. The side walls 4, 6 are substantially parallel to each other and / or substantially equal in width, its length being equal to the length of a partition wall and, consequently, at the height of the partition that it is being constructed. Interconnecting the side walls 4, 6 a along the respective edges, a sheet of separation 12 comprising a first and a second portion planar 14, 16 projecting from the respective walls lateral 4, 6 and a curved member 18 that interconnects the first and second planar portions. In the embodiment shown in Figure 1, the curved member is semicircular, so that if two identical partition posts were placed in mutual contact with their separation sheets 12 adjacent to each other, the respective curved members 18 would form a complete circle. Additionally, flanges 20, 22 extend inwardly from the free edges of the side walls 4, 6 and are substantially parallel to portions 14, 16.

Figure 2 shows a perspective view front of the post shown in Figure 1 and it can be seen that the curved member 18 has a series of longitudinal grooves 24 shaped along its length and, in the form of embodiment shown, along the central axis of the curved member 18. In preferred embodiments the length of the grooves longitudinal 24 is at least twice that of the portions of interconnection of the curved member 18. Contrary to expectations, it has been found that the incorporation of the curved member 18 and of slots 24 do not significantly weaken the partition post compared to standard "C" posts. Is considered that the curved member 18 introduces sufficient resilience in the partition wall to allow a certain flexion of the pole, which absorbs part of the transmitted vibratory energy on the partition wall 2 by the sound waves that affect members 8, 10 of the leaf partition. It is considered that slots 24 also improve the insulation qualities of post 2 sounds providing a physical break in the transmission path of the sound vibrations through the curved member 18. Slots 24 also minimize the material used in the separation sheet 12.

Also visible in Figure 2, is the plurality of pyramid-shaped depressions 26 that are formed on the outer surfaces of the side walls 4, 6. Depressions are preferably shaped by deep knurling of the side walls 4, 6 during the manufacture of post 2, although other processes of appropriate manufacturing. Similarly, other depressions formed may additionally or alternatively be incorporated, such as corrugations Each depression preferably has 2 mm 2 and 2 mm deep and are shaped in a repeated design of 2 mm apart from each other. Depressions increase stiffness of the side walls facilitating the fixing to them of the sheets of the septum material, for example using screws. Also more clearly visible in Figure 2 are located about grooves 28, 30 in acute angle formed within the respective side walls 4, 6 and directed towards each other.

Preferred partition wall dimensions 2 are as follows:

The separation sheet 12 can be between 40 mm and 150 mm wide.

The width of the curved member 18, or the diameter, can be approximately 1/3 of the total width of the separation sheet 12, the curved member 18 being located substantially in the central position in the sheet.

The width of the side walls 4, 6 can be between 32 mm and 52 mm.

The width of the flanges bent inwards 20, 22 can be between 6 mm and 12 mm.

The length of the slots 24 can be approximately 70 mm.

The separation of the slots 24 may be between 10 mm and 25 mm (this is the length with respect to the ratio of Slot spacing is approximately 3: 1).

The width of the slots 24 is approximately 1 mm and 4 mm.

Figure 3 illustrates an embodiment of the present invention in which more than one single row of elongated grooves along the curved member 18. In the embodiment shown in Figure 3 provides a first and a second row of slots 24, 25, the second being row of slots 25 shifted along the length of the curved member 18 at about half the length of a slot with respect to the first row of slots 24. The two rows of slots are separated at regular intervals over the curved member 18.

Figure 4 illustrates an embodiment additional that incorporates a first, a second and a third rows of elongated grooves 24, 25, 27 arranged along the extension of curved member 18, the third row being intermediate slot 27 displaced with respect to the first and second rows, 24, 25. In other embodiments they may additional rows of slots are arranged, preferably separated from regular intervals around the curved member 18.

By incorporating multiple rows of elongated grooves, post capacity is reduced to a greater extent to transmit sound waves. In the embodiments illustrated, it is preferable to move the rows of slots some with compared to others to maintain sufficient resistance within the post. However, other row arrangements may be used. of grooves in combination with the appropriate pole materials and the illustrated embodiments should not be considered as limiting the scope of the present invention.

An additional embodiment of a post of partition according to an embodiment of the present invention is shown in Figure 5. As in Figures 1 to 4, the post includes a first and a second planar portions 14, 16 interconnected by a curved member. In the embodiment of Figure 5, a row of diagonal grooves 24 ’is arranged inside the curved member. Extending the grooves over a substantial portion of the circumference of the curved member but not over its entirety

Figure 6 illustrates, in a plan view, a additional embodiment of the partition wall post according to The present invention. Post 2 has a fiberglass genre non-woven 32 extending through the open face of the curved member 18 and is fixed to the first and second portions 14, 16 of the separation sheet 12. A second non-woven fabric 34 extends between opposite surfaces of surfaces lateral 4, 6. The provision of non-woven fiberglass fabric Increase the effectiveness of post sound absorption of partition 2.

Figure 7 shows an embodiment alternative partition wall in accordance with this invention in which a sheet of absorbent material 36 sounds extends between opposite faces of the walls lateral 4, 6 substantially occupying the space defined by the side walls and by separating sheet 12 of post 2. The sound absorbing material 36 may be an insulator of fiberglass, nonwoven polyester wool or any other appropriate material. As regards the embodiment shown in Figure 3, the embodiment shown in the Figure 4 provides improved isolation efficiency to Post 2 sounds. Both embodiments shown in the Figures 3 and 4 reduce the sound transmission through the pole in approximately 2 dB.

An agreement partition wall construction With prior techniques it is schematically illustrated in Figure 8. Two parallel vertical posts 81 and 82 are arranged, to which fix a single sheet of partition plate or other material for walls 83. Each row of posts is located within a horizontal upper and lower trajectory. To add stiffness structural to the partition wall a brace 84 is fixed  between posts 81, 82. Bracket 84 has a resilient section 85 consisting of folded sections of the brace in an effort for reducing its sound transmission qualities.

The previous construction contrasts with that of the post partition illustrated in Figure 9 using a post 2 of according to embodiments of the present invention. In the illustrated embodiment the post 2 employed is substantially greater than prior art posts 81, 82 shown in Figure 8 and is located within the paths single upper and lower suitably sized. This allows the sheets of the partition plate 83 to be held to the outer face of the opposite side walls of post 2, while providing a free space between the plate sheets to partition that is substantially the same as the one offered by the prior art pole partition construction illustrated in Figure 8. Curved member 18 of post 2 provides a resilience similar to that offered by resilient portion 85 of brace 84 of the prior art.
